Abstract

The invention provides a head swinging mechanism and a medical anastomat, the head swinging mechanism comprises a rotating part and a head swinging pull rod, wherein when the rotating part rotates, the head swinging pull rod is driven to move in the axial direction of the anastomat; an elastic piece, at least part of the elastic piece is arranged on the outer side face of the rotating part in a protruding mode, the elastic piece comprises at least one protruding part, and the protruding part protrudes in the direction away from a rotating shaft of the rotating part; and a shell provided with a containing groove for containing the rotating part, wherein the inner side wall of the containing groove is provided with at least one notch, and when the rotating part rotates relative to the shell till the protruding part of the elastic part is opposite to the notch, at least part of the protruding part enters the notch. According to the invention, through the cooperation of the convex part of the elastic piece and the concave opening of the shell, an operator can conveniently set different swinging angles of the nail head part, and uncontrollable nail head part swinging can be avoided.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a head swing mechanism and a medical stapler. Background technique [0002] A linear stapler generally includes an instrument platform mounted on the head of the platform, and the head can pass through a small incision on the body through a puncture device to approach the surgical site for surgery. Specifically, the instrument platform includes a firing handle, and the head includes a nail box shell and a nail head installed on the far end side of the nail box shell. part. Driven by the firing handle, the firing assembly can drive the nail head to complete the suture cutting operation. [0003] In order to realize the swing of the nail head relative to the shell of the nail case, a swing head pull rod is arranged in the nail case shell, the proximal side of the swing head pull rod is connected to the swing head driving member, and the far end side of the swing head ...
